Homework Statement
A layer of ice having parallel sides floats on water. If light is incident on the upper surface of the ice at an angle of incidence of 15.0°, what is the angle of refraction in the water?
Homework Equations
The Attempt at a Solution
i know its not so simple that i can just use Sin theta n1 = sin theta n2... but i don't know how the fact that it is parallel will change the equation. Should i find the angle of refraction in the ice and then use that as the angle of incidence for the water?
